I think this is akin to saying that windows and doors are vulnerable to rocks and bump keys/battering rams, respectively. In the case that police take advantage of the real world counterparts, they're expected to have warrants despite the "vulnerability" because the owner has the expectation that most decent people (the general public) won't exploit it. The standard is whether a member of the public could happen to see inside, not whether it's feasible for them to if they really wanted to.
